A61g 9/00; E03d 13/00; A47k 11/12 13Claims ABSTRACT OF THE DISCLOSURE A disposable urinal having a generallycup-shaped hollow body provided with an enclosed end and an open end,and a hollow neck having opposite open ends, one of which iscompressively and sealingly engaged with the open end of the body, andprovided with a genitalia engaging opposite end having a rim adapted toconform with the female genitals for facilitating urination when afemale is in supine position; the body and neck structure of the urinalof the present invention being made of reasonably thin polystyrene orequivalent material.

Background of the inventionl In hospitals, conventional urinals andbedpans must be stored, transported, sterilized and thus are not onlybulky, but generally costly to maintain. Additionally, due to themaintenance problem, it has been necessary to employ conventionalurinals and bedpans, which of necessity, cannot conform closely to thegenitals of humans, especially females when in supine position. Theconventional urinals must have an opening of sufiicient size to permitproper cleaning maintenance. Additionally, it has been difficultproperly to place such conventional urinals, with respect to male orfemale patients, in a supine position, and to thereby maintain thepatient in a comfortable and clean condition during and after urination.

Additionally, various prior art urinals have been unsuccessful, from adisposable standpoint, due to the economy of producing suitablestructural features in a disposable urinal which may be used by humanmales or females during urination, when said male or females are insupine position. Some prior art urinals have been engagable with thegenitals of the human female, but have not properly fitted such genitalsin an area extending from the anterior wall of the vagina andintersecting the labia and so as to spread the labia to an area slightlyabove the clitoris, when a human female is in supine position.Furthermore, prior art urinals have not included an economicallyproducible structure which may readily be utilized and economicallydisposed of.

Summary of the invention The disposable urinal, in accordance with thepresent invention, is composed of two parts of very thin flexible andresilient material, one part being a substantially cupshaped containerbody having a peripheral n'm compressively and resiliently andfrictionally engaged with a complemental peripheral portion of a neckstructure of the urinal which is provided with opposite open ends. Theone end being compressively engaged with peripheral portion of thecontainer body while the urine receiving end is provided with a urinereceiving opening which, in the female variety, is provided with agenitals engaging rim structure adapted to provide for very sanitaryurination by a female when in supine position.

Accordingly, it is an object of the present invention to provide a verypractical and economical disposable urinal made of thin resilient andflexible plastic, such as high impact polystyrene, and such that ahollow neck may be produced separately from a generally cup-shapedcontainer body, such that these parts may be frictionally and sealinglyforced together to provide a very practical, useful, and extremelyeconomically produced disposable urinal.

Another object of the invention is to provide a very simple andeconomical urinal which greatly alleviates the maintenance cost ofurinals in hospitals, and further provides for additional comfort ofpatients, and particu larly female patients when urinating in a supineposition.

Another object of the invention is to provide a disposable urinal whichmay be made of very cheap plastic material, and which is so designedthat the parts thereof may be nested when transported or packaged tothereby greatly alleviate the overall cost of storage and maintenance ofurinals in hospitals or in other establishments.

Another object of the invention is to provide a disposable urinal ofnovel construction which also employs a human female genitalia engagingrim which extends generally from the anterior wall of the human vaginato a position slightly above the clitoris so as to comfortably fit thehuman female during urination, and to prevent undue spillage of urineduring urination of the human female, when in supine position.

Another object of the invention is to provide a novel disposable urinalcomprising a pair of very economically produced parts, namely, a hollowcontainer body part and a neck part, both subject to being nested inlarge numbers, and wherein the neck part may be frictionally andcompressively and sealingly engaged with the body part to form acomplete urinal when being readied for use.

Further objects and advantages of the invention may be apparent from thefollowing specification, appended claims, and accompanying drawings.

Brief description of the drawings FIG. 1 is a side elevational view of adisposable urinal in accordance with the present invention, and showingportions thereof broken away and in section to amplify the illustration;

FIG. 2 is a fragmentary view of the disposable urinal of the inventiontaken from the line 22 of FIG. 1;

FIG. 3 is an enlarged fragmentary sectional view taken from the line3--3 of FIG. 1; and

FIG. 4 is a diagrammatic longitudinal sectional view of the anatomy of ahuman female showing a disposable urinal of the invention in positionfor accommodating urination of the female in supine position.

Description .07 the preferred embodiments The disposable urinal of theinvention comprises a generally hollow cup-shaped body 10 and a neck 12.These two parts of the disposable urinal of the invention may, forexample, be very economically made of high impact polystyrene orequivalent material, this material being as thin or less than 30thousandths of an inch, as

desired. Accordingly, these parts may be very economically manufactured.

The hllow-cupshaped body is generally annular, as indicated in FIGS. 1and 2, and of a tapered body design, such that large numbers of thesehollow cupshaped container bodies may be transported or stored in nestedcondition.

Likewise, a plurality of the necks 12 may also be stored in nestedcondition since they are generally frusto conical in shape.

The container body 10 is provided with a normally enclosed lower end 14and a peripheral portion 16 within which a peripheral portion 18 of theneck 12 is compressively, sealingly, and frictionally disposed.

Referring to FIG. 3 of the drawings, details of the peripheral portions16 and 18 may be observed. The container body 10 is provided with agenerally annular internal groove portion 20 in which the peripheralportion 18 of the neck 12 is compressively, sealingly, and frictionallyheld. This peripheral portion 18 is provided with a rolled edge portion22 which is slightly larger in diameter than the internal groove portion20, but due to the resilient compressive character of the material ofboth the body 10 and neck 12, the peripheral portion 18 of the neck 12may be forced internally of the peripheral portion 16 of the containerbody 10, and brought to a compressive locking position in the groove 20.The rolled edge 22 is normally of slightly larger diameter than thegroove 20, and thus provides for a .very tight seal and frictional fitof the peripheral portion 18 in the groove 20 of the peripheral portion16.

It will be understood that these parts may be manually assembled bypressing the peripheral portion 18 of the neck 12 into the peripheralportion 16 of the container body 10.

The neck 12 is provided with a first open end 24 surrounded by theperipheral portion 18, and a second open end 26 having a genitalengaging rim 28 which is generally pear-shaped, as shown in FIG. 2 ofthe drawings. The rim 28 is provided with an inwardly directed flange 30forming a substantially U-shaped in cross-section genitals engagingledge, and the ledge 30 is disposed in a plane at an angle to the openend of the: container body 10 about which the peripheral portion 16 isdisposed. The angle of the ledge 30 can be seen to have a properrelation to urination of a human female when a supine position, asindicated in FIG. 4 of the drawings.

The ledge 30 at the rim 28 is provided with a slightly hooked portion 32adapted to engage the anterior wall of the vagina, as shown in FIG. 4 ofthe drawings, while an opposed rim portion 34 is adapted to engage thefemale genitalia at a location above the clitoris and in the area of theprepuce, as shown in FIG. 4 of the drawlngs.

As shown in FIG. 4 of the drawings, the walls of the neck 12 and thebody 10 are disposed in a downward declining attitude below the urethralorifice of the patient, when said rim 28 is properly engaged with thegenitals of a human female in supine position.

It will be seen that the portion 32 is opposed to the portion 34, andthat the portion of the rim 28 at 34 is on a long radius, while theportion 32 is on a relatively shorter radius causing the opening 26 andthe rim 28 to be generally pear-shaped, as indicated best in FIG. 2 ofthe drawings.

Adjacent to the larger radius portion 34 is a vent opening 36 which isadapted to be located uppermost and closely adjacent the area of the rim28 which normally engages the area of the prepuce of the female, when insupine position, as shown in FIG. 4 of the drawings.

It will be seen that the thickness of the material, as shown in thedrawings, is exaggerated, and it will therefore be appreciated by thoseskilled in the art that the actual wall thicknesses of the parts aremuch thinner and consequently very economical to produce in terms of theamount of material utilized to produce each disposable urinal, inaccordance with the present invention.

Due to the high impact polystyrene characteristics, the parts may beresiliently and frictionally forced together at their peripheralportions, as shown in FIG. 3, and as hereinbefore described, and thatthe neck parts may be nested as well as the body parts, and that theindividual neck parts and body parts may be readily and easily assembledimmediately prior to use, as indicated in FIG. 4 of the drawings.

It will be obvious to those skilled in the art that variousmodifications of the present invention may be resorted to in a mannerlimited only by a just interpretation of the following claims.
